MARTINEZ — A retired Contra Costa Fire District captain at his arraignment on Tuesday pleaded not guilty to stealing property from district firehouses.

Jon Wilmot, 53, held over for trial after a recent preliminary examination, is charged with receiving stolen property. Prosecutors say Wilmot stole hundreds of items from district fire stations, ranging from pencils to chain saws.

Arrested in December 2012, Wilmot — who is not in custody — appeared in court Tuesday. His next court appearance is scheduled for April 29.
